Andrew:
The law in this area is both complex and relatively untested, but here
goes:
If the email has been delivered to the PC being remotely investigated
then I think the argument would be that there is no interception so that
s 17 RIPA would not apply (in the way it would if you had set up a
monitorung device between the PC and the owner's ISP and had captured
the email in transit). I do recognise, though, there'd be an
interesting case to be made in respect of an email delivered to the PC
but not yet read by the owner - a fact which could be established by
looking at the flags within the email archive.
The technique can be used for anything on the PC including deleted but
recoverable material. If by any chance an investigator or prosecutor
became worried that particular classes of material might be inadmissible
they could then seek to make their case with material that was
definitely admissible. After all, that is how intercept material is
used today - the inadmissible content of the phone call tells the
investigators that the narcotics shipment is arriving/that a bomb
factory is in operation at a certain location, etc etc, the police turn
up and seize enough evidence to secure the conviction.
